30 I/O Allocation and Program 6.1 I/O Number of A/D Converter Unit About the conversion data switch flags The resolution of the A/D converter unit is 12 bits, but when data is transferred to the control unit, it is converted to 16-bit data. Therefore, although the W2 data requires no processing, for the W3 data, the top two bits are used as conversion data switching flags. Accordingly, the top two bits are processed as follows. When the A/D conversion data is negative, the W2 and W3 data become two s complement. In other words, bit C to bit F of W2 and bit C to bit D of W3 become 1. Also, because the top two bits of W3 are used as conversion data switch flags, masking is required so that the bits are 00 when the conversion data is positive +, and 11 when the conversion data is negative. ch3 data W3 Data after masking Conversion data switch flags Mask applied to the above values 6-4
